“Lake Louise is eager to move forward and initiate the remediation plan we’ve been working on in co-operation with Parks Canada.”

The long-lived, five-needle whitebark pine is native to high elevations and is threatened by invasive disease, fire and climate change. It is considered crucial because it provides food and habitat for animals and helps stabilize steep subalpine slopes.

The tree exists at high elevations in western North America at or close to the treeline. It has been growing on the continent for 100,000 years and can grow to be between 500 and 1,000 years old.

An agreed statement of facts says a trail crew, consisting of six employees including a supervisor, began maintenance in the summer of 2013 on Ptarmigan Ridge at the ski resort. The work involved cleaning up, repairing and erecting fences, and trimming and removing some trees.

The document says that in late September of that year, the workers cut down a number of trees, including endangered whitebark pine, without a permit.

The facts statement says it wasn’t until Aug. 12, 2014, that Parks Canada and resort personnel who were assessing the site for a new hiking trail discovered the endangered trees had been cut.

DNA analysis confirmed the trees were whitebark pine. The matter was turned over to Parks Canada for an investigation and charges were laid.

The court document says Lake Louise was co-operative during the investigation and has taken steps to prevent similar occurrences. It says the resort has also spent money on initiatives related to the whitebark pine, including extensive mapping of that tree in the area.
